Auto-voip on SG3428
I'm a little bit struggling, I need some help in configuring auto voip on sg3428. So I have a Cisco router that has dhcp pool, one for the native vlan which is 1 and the second is for the ip phone. A port from the router is directly connected to the switch which has the ip phones (vlan 30), another port is connected to a dlink switch and from the dlink to the tplink for the native vlan (vlan 1) So when I plug the phone on the router directly, It get an ip in the 10.10.30.0 (the desired network). I have created a vlan 30 and activate auto voip globally, on the interfaces that connect the phone and pcs ( switchport general allowed vlan 1 untagged, switchport general allowed vlan 30 tagged) activate lldp and lldp-med globally, set the port between my switch and the router on trunk with switchport general allowed vlan 1,30 tagged. When i plug ghe yealink phone on the switch i get the 10.10.30.x and 10.10.30.x on the pc also, but the internet is down on the pc. I have searched for similar scenarios with yealink ip phones and tplink switches but I didn't found anything. I founded a guide for the auto voip on tplink website but the same thing. If u can help I will be appreciated.
